I had this unit. Not too impressed with it's features or the navigation stick. You cannot put in expandable memory like the one I bought.
what did u buy?
Bought the Magellan Gold for $200. Expandible memory slot is great for downloading maps and/or adding Direct Route which will guide you to your destination with beeps and arrows on the screen. It also can take a lot of abuse. Only thing I wish is for it to be color, but at the time was $150 difference.
